Tyre ie 205 times the profile ie .45 times two (both sidewalls) then add the rim size ie 17 x 25.4. And the times by pi to get the circumference (not necessary needed you can work out the difference just by the diameter as pi is a constant in both).

(205 x .45 x 2) + (17x25.4) = 616.3mm Wink

Alternatively just post the tyre width and profile of both tyres and i'll do the calcs for you.
